The innovation landscape of South Africa under new intellectual property management policy
(Innovation Summit, 2013)
The new intellectual property (IP) policy currently under development by the Department of Trade and Industry will likely define the future innovation landscape in South Africa. This is in line with the direction the country ...
The challenges of implementing gravel road management system in Sub-Sahara Africa: Tanzania case study
(Delhi : IJARES, 2014)
The study examined the working environment of road organizations in Tanzania mainland implementing gravel road management system. These road organizations falls into two categories, namely those managing district roads ...
Controller performance assessment of servomechanisms for nonlinear process control systems
Abstract—This paper aims at assessing the setpoint tracking performance of proportional-integral-derivative (PID) controllers for nonlinear single-input-single-output (SISO) process loops. A comparison is made between the ...
Eco-efficient criteria : sustainability
(3S Media, 2014-04)
There is an urgent need to apply cost-effective technologies and methods that deliver better and more sustainable performances.
Development and evaluation of woven fabric microﬁltration membranes impregnated with silver nanoparticles for potable water treatment
Access to clean and safe drinking water is a fundamental human need, which is commonly lacking in remote rural areas. A simple gravity-fed water treatment unit was developed based on woven fabric microﬁltration (WFMF) ...
Minimum weight design of beams against failure under uncertain loading by convex analysis
Under operational conditions, some loads acting on a beam are known (deterministic loads), but there usually exist other loads the magnitude and distribution of which are unpredictable (uncertain loads). If the uncertainty ...
The purification of corn steep liquor as a fermentation feedstock by ultrafiltration
THE OBJECTIVE of this study was to devise a purification process, using ultrafiltration membranes as the core technology, for the preparation of corn steep liquor (CSL) as a fermentation feedstock. This process inherently ...
Object motion detection, extraction and filtering using ANN ensembles
This research is devoted to the development of an intelligent image motion detection system based on artificial neural networks (ANN’s). Object motion detection, non-stationary image isolation and extraction, and image ...
A technique for stiffness improvement by optimization of fiber steering in composite plates
A methodology for stiffness improvement by optimal orientation of fibers placed using fiber steering techniques of composite plates has been developed and is described here. A genetic algorithm is employed to determine the ...
A procedure to select the best material combinations and optimally design hybrid composite plates for minimum weight and cost
(Taylor & Francis, 1997)
The optimal layup with least weight or cost for a symmetrically laminated plate subject to a buckling load is determined using a hybrid composite construction. A hybrid construction provides further tailoring capabilities ...
